Edexcel, a Pearson company, is the UK’s largest awarding body, offering academic
and vocational qualifications and testing to more than 25,000 schools, colleges,
employers and other places of learning in the UK and in over 100 countries
worldwide. Qualifications include GCSE, AS and A Level, NVQ and our BTEC suite of
vocational qualifications from entry level to BTEC Higher National Diplomas,
recognised by employers and higher education institutions worldwide.
We deliver 9.4 million exam scripts each year, with more than 90% of exam papers
marked onscreen annually. As part of Pearson, Edexcel continues to invest in cuttingedge technology that has revolutionised the examinations and assessment system.
This includes the ability to provide detailed performance data to teachers and
students which helps to raise attainment.
